Technical Information

The Product Configuration Model Code (model code) is used to specify particular features when ordering a JS2000 joystick. The model code begins with the product family name JS2000 and the remaining fields are filled in to configure the product with the desired features.

The model code includes both joystick base and joystick grip information.

Output Sense (Direction)

The dual outputs from any JS2000 joystick can be configured in one of two possible ways. These are designated within the joystick model code as same sense (P) or opposite

sense (N). Refer to the output sense (direction) diagram, page 6 for clarification.

The slopes at the lower end start at 20% of supply voltage range (Vs) and at the upper end finish at 80% of Vs.

In the same sense configuration, the outputs of an axis can be directly compared to determine the serviceability of the joystick. In the opposite sense configuration, the sum of the outputs from any axis should be equal to the applied voltage.

Code Description Axis Option

Dual JS2000 Output Signals (X and XY options)

Each joystick axis is equipped with two outputs and it is recommended that both outputs are continuously compared to ensure that the difference does not exceed the maximum specified difference plus an appropriate safety margin. In addition, machine movement should not be enabled until both outputs from any one axis exceed the center threshold voltage plus a suitable safety margin (for example twice the joystick center deadband).

The outputs in normal use should be within the limits 0.35 to 4.65 V DC. Any output significantly outside of this range must be regarded as erroneous and appropriate safe action taken. A high value pull-up or pull-down resistance should be added to the X and Y outputs such that in the unlikely event of a wire or connector failure, the output will be pulled out of range.

Single Outputs (XYZ option)

Where a joystick incorporating only a single sensor per axis is used to control safety critical functions, an independent momentary action system enable switch should be provided.

Center Tap

A center tap is provided as a means of verifying the integrity of the Vs at the joystick. Clearly a high resistance or open circuit in either the Vs or ground connections will affect the joystick outputs. The normal output at the center tap connection is 49.16 to 50.84% of Vs. A center tap output outside this range indicates a fault in the supply to the joystick Hall sensors.

Output Impedance

Joystick outputs at the center position and the end of travel are specified with infinite load impedance or zero current. The effect of adding finite load impedance will be to source or sink current through the joystick output impedance. The voltage dropped through the joystick output impedance must be taken into account when the system threshold voltages are being defined.

RECOMMENDED WIRING PRACTICE

Product Installation

All Wires must be protected from mechanical abuse.

Use 85° C wire with abrasion resistant insulation.

Separate high current wires such as solenoids, lights, alternators, or fuel pumps from

control wires. Recommended minimum separation is 300 mm [11.8 in].

Run wires along the inside of or close to metal machine frame surfaces where

possible. This simulates a shield which will minimize the effects of EMI/RFI radiation.

Do not run wires near sharp metal corners. Consider running wire through

grommets when rounding a corner.

Provide strain relief for all wires.

Avoid running wires near moving or vibrating components.

Avoid long, unsupported wire spans.

All sensors have dedicated wired power sources and ground returns.

They should be used.

Sensor lines should be twisted about one turn every 100 mm [3.94 in].

It is better to use wire harness anchors that will allow wires to float with respect to
(12)

Technical Information

Prior to installation, check that the travel limiter gate positioned under the boot at

the top of the joystick is correctly located and oriented.

The joystick is sealed above the mounting surface to prevent dust and water

Ingress to IP 65 and is supplied with mounting hardware (sealing gasket and trim plate suitable for mounting from above the panel. The effectiveness of the seal is dependent on the mounting surface being sufficiently rigid to compress the sealing gasket. The finish of the mounting surface is critical to achieving an adequate seal and rough surface finishes, paint chips, deep scratches, etc should be avoided. It is possible to mount the JS2000 from under the panel surface by discarding the trim plate and compressing the base of the flexible boot against the panel and mounting flange.

The joystick base below the mounting surface should be protected from dust and

direct water spray.

Joystick Safety

For a system to operate safely it must be able to differentiate between commanded and uncommanded inputs. System designers should take steps to detect and manage joystick and system failures that may cause an erroneous output.

For safety critical functions it is recommended that an independent momentary action

system enable switch be used. This switch can be incorporated into the joystick as a operator present switch or can be a separate foot or hand operated momentary switch.

All functions controlled by the joystick should be disabled when this switch is released. The control system should look for the appropriate system enable switch input before the joystick is displaced from its neutral position. Functions enabled by the joystick should not be enabled until this input is received.

Output Noise

The JS2000 incorporated Hall effect sensors to detect the position of each of the joystick axes. A side effect of the use of these sensors is electrical noise superimposed on the output signal, nominally 20 mV peak to peak. The application program can filter out this noise.

Magnetic immunity

The use of the JS2000 in close proximity to sources of high magnetic fields is not recommended.

Supply voltage

The JS2000 is designed to operate from a regulated 5 V DC ± 0.5 V DC supply that is free from transients. Joystick outputs are ratiometric and are therefore a function of the input voltage.
